Update:
The matt films have arrived together with the car cradle of Mumbi (whose review is subject to the relevant product). Again, I have to say that the films are very precisely cut and I, despite some exercise (all my smartphones get films) had put the first slide after several attempts aside because they had despite all precautions sometime times but gotten a finger and thus not more one hundred percent stuck. But in the second film (as almost always) had then folded it. The old trick, by means of a strip of adhesive tape to remove the last particle of dust that had then still smuggled, the film now sits perfectly on the display. The display of Z2 is now indeed barely noticeable dark, but nothing more is reflected in it. The sensitivity of the display has not suffered, it is just as quick to operate as before. I am particularly pleased that you can not see the annoying fingerprints on the display, which had me very annoyed at the clear films and in the time until the film arrived to me in the mail, on the unprotected display yet. Several times a day I had to remove it from the display. Now, with the matt films I have my microfiber cloth not even have to take at hand in the last 2 days.
I had my first telephone contact with the service and am very pleasantly surprised. Because of the failure of the first experiment with the matt film has there without that I have asked immediately arrange to send a free replacement. Since I had applied as a tester for more Mumbi products using the postage-paid postcard enclosed in this delivery, my another product from the house of Mumbi was immediately offered to test that I can test for a longer period and should be retained for a feedback. That is all around in every way an excellent service, I know only from higher price regions so.
In summary: A very good product, delivered quickly work as described was perfectly clearly exceeded with a service of my expectations. I highly recommend the film and also the car cradle only warmly.
